Obviously someone made those apex seals.. Perhaps they have been used in an expereriment. Finally something posted in the lounge that's unique in content.

 

don't have one, we where talking about them with a rotor shop guy at the last rx meet. i'll see if he has any info on them

 

I have no idea why this thread went as far as it did.

CF Apex seals..... I don't think so, but if someone makes them and they work really well, I'll gladly eat crow while I get in line to buy some.

 

that's carbon ceramic or ceramic carbide not carbon fiber. Big difference.

 

just think about how happy my manifold will be

 

Theoretically, if I were to know your idea, what would it be? Theoretically

 

did anyone else notice one was broken? couldn't have worked out all that well

 

THANK YOU i was jsut about to respond to that... i think they were a joke.....

 

Ok brace yourself...













SPIDER SILK!

 

Maybe I'm just retarded, but what the hell would the purpose of carbon seals be? It's not for weight, I assume. I mean, that's like .5 lbs you'd be saving. Totally not worth the process/time/money of carbon seals.. Maybe it's just me.

 

pfft....been there...tried that...blew up after 1500 miles

 

Care to elaborate? Someone actually made seals from spider steel?

 

Yeah, but I bet it didn't chew up your housings on the way out.

 

it's not weight reduction off the vehicle, but if you spin something around in a figure 8 pattern at high rpm's, a lighter weight seal will move around a lot faster and seal better, instead of bouncing along the rotor housing.

benefits of lighter seals are more hp, torque, and fuel economy, and less chatter on the rotor housings at high rpm.

 

no one has actually ever heard of Carbon race Apex seals? wow.... I have read about these and thought about them for a while now, downfalls are they are not recommended for Turbo or nitrous applications, good points are they will not chatter until a much higher rpm than stock steel ones and they are cheaper. great for a full N/A build if you dont mind rebuilding it every 20k miles according to them, however a local racer built his engine and ran them 10k miles, when they came out they had very minimal wear.

There is a link to them on Mazdatrix.

Carbon apex seals are far different then carbon fibre apex seals. Carbon seals have been in use for a long, long time. They're not really street seals though as the main advantage of a carbon seal is that they don't take out a housing when they blow, not long life. They also don't seal well at low RPMs...

 

imma use depleted uranium.

if they can absorb the impact from a 50mm round, they can probably handle detonation

 

Ok, i dont know why i waited so long to write a reply to this, but here it goes.

I'm no pro, but i have been dealing with CF and fiberglass for some time now. I can tell you that these 'carbon fiber' apex seals are some sort of joke. You know, CF will catch fire if you put a match to it... What do you think would happen if you put it in a fire breathing rotary?

then theres the problem with resins as stated above.

tho, I am impressed how uniform the made these. It seems the weave of the fabric is uniform on all three of the seals. maybe this wasnt for a gas engine?

What is the link to the site this was found on? Some of us can read japanese!

 

did you even see the pic of me blasting the carbon fiber with a blow torch? i only made it glow for 10-15 seconds, but i'd assume that's enough to know it's not gonna catch on fire.

 

Notice that if you do this, there will be a black feathered mess left. That is the actual carbon fiber; the resin is the onyl part that burns.

Another stupid idea...
DU apex seals would eat everything else up inside the engine.

And that other pic with the torch...
Yes, the raw carbon fiber material is very heat resistant.
"Carbon fiber composite" or "Carbon Fiber Reinforced Plastic" (CFRP) using resins or epoxies - which most people think about when you mention "carbon fiber" - will catch on fire with that same torch.

Those apex seals are not "carbon fiber" as it has been pointed out.
Carbon apex seals are not recommended for boosted applications.
They are used for high-revving NA motors.

Hey, I saw a Porsche flat 6 na engine that used carbon fiber pistons that had been ceramic coated. I’ll try to remember the name of the company…..it was a test engine…I don’t know how the test turned out.

 

speaking of stupid, you don't even know a joke when you hear it.

and since you're a metallurgist, you know that uranium is a very soft metal. why do you think they use it on tank armor? because it absorbs and bends, rather than cracks.

 

now the ceramic/carbon might be a good idea. worth testing.

 

I'm going to make seals out of dry Ice then I'm going to convert my car over to run on thermite.
